Example one
The locking adjustment mechanism of wearing equipment that this embodiment provided is applied to wearing equipment such as VR glasses, intelligent glasses in, through optimizing its structure for the user can dress more conveniently or take off wearing equipment, has optimized user's use and has experienced.
As shown in fig. 1 and fig. 2, the locking adjustment mechanism of the head-mounted device of the present embodiment includes a housing, the housing is slidably connected with an expansion band assembly 10, the housing is rotatably connected with a knob unit 20, and a limiting base 30 and a driving member 40 are sequentially disposed between the expansion band assembly 10 and the knob unit 20; one end of the driving member 40 passes through the limiting base 30 and is connected with the telescopic strap assembly 10 for driving the telescopic strap assembly 10 to extend out of or retract into the housing, and the other end of the driving member 40 is connected with the knob unit 20. The housing comprises a front housing 51 and a rear housing 52, a cavity is formed between the front housing 51 and the rear housing 52, and the telescopic band assembly 10, the knob unit 20, the limiting base 30 and the driving member 40 are all installed in the cavity; the telescopic belt assembly 10 specifically comprises a first telescopic belt 11 and a second telescopic belt 12 which are arranged on the left and right, wherein openings are formed in the first telescopic belt 11 and the second telescopic belt 12, a first transmission part is formed on the lower wall surface of the opening of the first telescopic belt 11, and a second transmission part is formed on the upper wall surface of the opening of the second telescopic belt 12, so that the movement directions of the first telescopic belt 11 and the second telescopic belt 12 are opposite; when the driving member 40 rotates, the first retractable belt 11 and the second retractable belt 12 can be driven to move toward or away from each other, so as to extend or retract the retractable belt assembly 10.
The wall surface of the limit base 30 facing the knob unit 20 is provided with a first limit portion 31, and the driving member 40 is provided with a second limit portion 41.
When the retractable strap assembly 10 abuts against the driving member 40 and the driving member 40 is subjected to a force in the first direction, the second stopper portion 41 abuts against the first stopper portion 31. For example, when the user wears the headgear, the retraction strap assembly 10 tends to extend outward, thereby causing the driving member 40 to tend to rotate in the first direction, and at this time, the second position-limiting portion 41 interferes with the first position-limiting portion 31 to counteract the tendency to rotate, thereby maintaining the amount of retraction of the retraction strap assembly 10.
When a user needs to adjust the expansion amount of the telescopic strap assembly 10, the knob unit 20 is rotated in a first direction to extend the telescopic strap assembly 10, and the knob unit 20 is rotated in a second direction to retract the telescopic strap assembly 10; in the above process, when the knob unit 20 is rotated in the first direction, the second stopper portion 41 is dragged by the knob unit 20 to move in a direction away from the first stopper portion 31, and the retractable strip assembly 10 is extended out of the housing. Since the second position-limiting portion 41 abuts against the first position-limiting portion 31 when the driving member 40 rotates in the first direction, the second position-limiting portion 41 can move relative to the first position-limiting portion 31 when the knob unit 20 rotates in the second direction, and the telescopic strap assembly 10 retracts into the housing.
Therefore, when the telescopic strap assembly 10 needs to be retracted, the user rotates the knob unit 20 in the second direction, and the first stopper portion 31 does not block the second stopper portion 41, so that the driving member 40 can be rotated in the second direction, and the telescopic strap assembly 10 is retracted into the housing; when the telescopic strap assembly 10 needs to be extended, the user rotates the knob unit 20 in the first direction, and at this time, the second limiting portion 41 is dragged by the knob unit 20 in the direction away from the first limiting portion 31, so that the driving member 40 can rotate in the first direction, and the telescopic strap assembly 10 is extended out of the housing; meanwhile, after the adjustment is completed, if the retractable belt assembly 10 is subjected to an external force, it tends to extend out of the housing, that is, it tends to drive the driving member 40 to rotate along the first direction, because the knob unit 20 does not rotate along the first direction, the second limiting portion 41 does not tend to move along a direction away from the first limiting portion 31, which is equivalent to the first limiting portion 31 and the second limiting portion 41 abutting against each other, the driving member 40 is prevented from rotating, so that the retractable belt assembly 10 overcomes the external force and does not extend out of the housing any more, and the tightness of the head-mounted device is maintained; therefore, the user can adjust the tightness of the head-mounted device by operating the knob unit 20 with one hand, and the user experience is improved.
In the present embodiment, the first position-limiting portion 31 is a rigid position-limiting portion, and the second position-limiting portion 41 is an elastic position-limiting portion. Because the second limiting part 41 is an elastic limiting part, after the user adjusts the rotation angle of the driving part 40, the second limiting part 41 can reset under the elasticity of the user, so that the clamping effect of the first limiting part 31 and the second limiting part 41 is realized, and the space utilization rate is high. In other alternative embodiments, the first position-limiting portion 31 and the second position-limiting portion 41 are both rigid position-limiting portions, but an additional structure similar to a spring is required to be configured, so that the second position-limiting portion 41 can be reset after being dragged by the knob unit 20.
In one specific embodiment, as shown in fig. 4 to 7, the first position-limiting portion 31 includes a position-limiting platform 311 protruding from the position-limiting base 30, and a tooth-shaped groove 312 is formed on the position-limiting platform 311. The second position-limiting portion 41 includes an extension arm portion 411 disposed on the driving member 40, and a tooth-shaped portion 412 is protruded from an end of the extension arm portion 411 along the first direction, and a profile of the tooth-shaped portion 412 matches a profile of the tooth-shaped groove 312. The specific tooth shapes of the tooth-shaped groove 312 and the tooth-shaped portion 412 are not limited, and straight teeth, helical teeth, etc. may be used.
As shown in fig. 8 to 9, the distance between the extension arm 411 and the knob unit 20 is greater than the minimum distance for the tooth 412 to escape from the tooth groove 312. For example, when the knob unit 20 is not rotated, the tooth-shaped portion 412 is engaged with the tooth-shaped groove 312, and even if the retractable belt assembly 10 is subjected to an external force to drive the driving member 40 to rotate, the force acting between the tooth-shaped portion 412 and the tooth-shaped groove 312 can counteract the tendency. It should be understood that, when the retractable belt assembly 10 needs to be retracted, the user rotates the knob unit 20 in the second direction, at this time, the direction of the force applied to the tooth-shaped portion 412 is opposite to the first direction, the extension arm portion 411 is equivalently applied with a compressed force, and due to the limiting effect of the tooth-shaped groove 312, the extension arm portion 411 is deformed in the direction away from the tooth-shaped groove 312, so as to drive the tooth-shaped portion 412 to disengage from the tooth-shaped groove 312, so that the knob unit 20 can drive the retractable belt assembly 10 to retract through the driving member 40. Therefore, in the present embodiment, the elastic deformation of the second stopper portion 41 is realized by the extension arm portion 411, which saves parts and space and reduces the cost.
In other alternative embodiments, the second position-limiting portion 41 may also be configured similar to a pawl, but correspondingly, a torsion spring is required to be configured at the connection between the pawl and the driving member 40 to realize the deformation of the pawl.
Further, as shown in fig. 5 and 6, a gear portion 42 is formed at one end of the driving member 40, and a knob stopper disc 43 is formed at the other end of the driving member 40. The knob stopper 43 has a plurality of mounting grooves 44 formed along a circumferential direction thereof, an extension arm 411 extends outward from a first groove wall 441 of the mounting groove 44 along the first direction, and a gap is formed between the tooth-shaped portion 412 and a second groove wall 442 of the mounting groove 44. Wherein the gear portion 42 can mesh with the first transmission portion and the second transmission portion to realize the extension or retraction of the telescopic band assembly 10; meanwhile, the gear part 42 and the knob limiting disc 43 are of a convex structure, the extension arm part 411 is arranged in the mounting groove 44 of the knob limiting disc 43, the overall space layout is optimized, the whole body is more compact, in addition, the extension arm part 411 is arranged in the mounting groove 44, the interference of other parts to the extension arm part is avoided, the extension arm part 411 can only be in contact with the knob unit 20, the tooth-shaped part 412 can only be in contact with the tooth-shaped groove 312, and the overall stability is improved.
Further, as shown in fig. 3, 6 and 7, a snap mounting hole 45 is formed between the second position-limiting portion 41 and the groove wall of the mounting groove 44 along a direction perpendicular to the first direction. The knob unit 20 is provided with a snap connection portion 21 at a position corresponding to the snap mounting hole 45, and the snap connection portion 21 is sleeved outside the extension arm portion 411.
When the knob unit 20 is rotated in the second direction, the snap connection 21 abuts against the first groove wall 441. The knob unit 20 drives the extension arm portion 411 and the tooth-shaped portion 412 to rotate in the first direction by the abutting between the snap connection portion 21 and the first groove wall 441, and since the acting force is applied to the first groove wall 441 and does not directly act on the extension arm portion 411, the influence on the extension arm portion 411 can be reduced, the extension arm portion 411 can be jacked up by the tooth-shaped groove 312 under the extending action of the extension arm portion 411, the relative movement between the tooth-shaped portion 412 and the tooth-shaped groove 312 is realized, and the stability of transmission is ensured.
When the knob unit 20 is rotated in the first direction, the snap connection portion 21 abuts against the tooth portion 412. That is, the snap connection 21 pushes the tooth-shaped portion 412, so that the tooth-shaped portion 412 is disengaged from the tooth-shaped groove 312.
Further, a slope 413 is formed between the extension arm 411 and the tooth 412. When the knob unit 20 rotates along the first direction, the snap connection portion 21 abuts against the slope portion 413, so that the second position-limiting portion 41 moves relative to the first position-limiting portion 31. Through the setting of slope portion 413, avoid buckle connecting portion 21 direct action with profile of tooth portion 412, reduced the wearing and tearing of profile of tooth portion 412, and then improved holistic life-span.
Further, as shown in fig. 7, the snap connection portion 21 includes two oppositely disposed snap units, and the extension arm portion 411 is disposed between the two snap units. In other alternative embodiments, the snap connection 21 includes one snap unit, and the snap unit is disposed at one side of the extension arm 411.
Further, as shown in fig. 2, the limit base 30 is provided with a knob mounting portion 32 protruding from the limit table 311, and a knob rotating groove 33 is formed between the knob mounting portion 32 and the limit table 311. Meanwhile, the knob unit 20 is correspondingly provided with the accommodating groove 22, the groove edge of the accommodating groove 22 can be sleeved in the knob rotating groove 33 to achieve the effect of auxiliary positioning, and on the other hand, the limiting table 311 can be correspondingly arranged in the accommodating groove 22, so that the compactness of the whole structure is further improved.
Further, as shown in fig. 2, the limiting base 30 is provided with an avoiding hole 34 for the driving member 40 to pass through, and the avoiding hole 34 passes through the limiting table 311 and the limiting base 30. The limiting base 30 is further convexly provided with a gear baffle 35 at one side far away from the limiting table 311, and the gear baffle 35 is arranged outside the avoiding hole 34. Among them, the gear guard 35 plays a role of protecting the gear portion 42.
